Start slow and keep in mind that hands are some of the best toys around. Spanking is a lot of fun if you or your partner enjoy pain. Same thing goes for nipple clamps (there are some good ones on EF, but if you want to see if you like it before buying anything, clothespins are incredibly cheap and make decent clamps). Resistance play (holding your partner down or being held down by your partner) is also a good place to start, since you can easily vary the intensity. It can start with wrist-grabbing and gentle pinning now and evolve into intense rope bondage down the line if you're interested.

Most importantly, make sure you and your partner openly discuss your specific interests with one another. BDSM is a very broad field, so determining precisely what you and your partner want to try is important. I hope that helps! Play safe and have fun
